Google Pagerank Simplified Formula!

I don't believe this,infact I would consider this to be fake.The general concept for the PR formula is
PR(A)=(1-d)+(PR OF LINK PAGE 1*D/NO OF LINKS IN PAGE1)+ (PR OF LINK PAGE 2*D/NO OF LINKS IN PAGE2)+.....+(PR OF LINK PAGE P*D/NO OF LINKS IN PAGE P).

Where A,is your website
D is a damping factor =0.85
link page 1,2...,P are the pages that has a link pointing to your website and can be found out by clicking on the arrow situated besides your PR bar.It would give you three options a)Cached snapshot,b)related pages and c)backlinks.
Still if you are unaware of the PR concept it is suggested that you use the PR calculator.
More over with Google you never know what algorithms they are implementing when they conduct an update.What matters mostly is the age of the domain.When I started out it was obvious that I had a 0PR. got my page cached and then I had a PR of 3 with backlinks of 36.In october last year when Google crawled I had an increase in PR to 4 and backlinks went up to 52.This January my backlinks went up to 265 but there wasn't an increase in my PR. Last week the last update Google made on PR and backlinks saw my PR reduce to 3 and my backlinks shot down to 121.What matters for Google is that the page of the site were your link is placed should be cached.For that to happen you have to upload it with fresh content on a regular basis.
Page rank is dependent primarily on the backlinks or the inbound links that you have.The age of domain matters too.If Google finds more links pointing to your website compared to your website's age your IP address might just get banned.

 

I am sorry but I am quite sure this is all wrong. I have two personal experiences that bring your theory down:

1. I had a PR7 site (equal to 53,310,378 points in your half pyramiod) for one link (and one link only) from a PR8 page (140,958 points). Even if it was related, that means like 1 million points most. There were like 2 outgoing links only on my page.
2. I have a PR5 (PR6 before) site with half a million backlinks from pages between PR0 and PR6 (mostly PR3 and PR4). If I count all the links, I am pretty sure they will lead me to PR8 at least. There were 5 outgoing links only and now 10.

So, it is not as simple as adding points together but much of understanding google's thinking and algo.

 

Good job whiteblue1942 - this is the clearest description I've seen. Keep us updated on your findings.

...I'm off to see how close my site is to becoming a PR4

 

If you are not reaching your predicted pagerank and feel you should have a higher ranking accorign to this formula, then google punished you for some reason, most likely buying or selling links. and im sure if you have half a million links w/ a pr5 site then you have done this quite a bit! Google takes away a portion of ur PRranking for MANY REASONS.

So if your not getting ur expected pr chances are you did somthing wrong that violated googles terms of service!

 

I'm wondering why didn't you take into consideration the number of outbound links of the website which is passing the PR.

You simply can't say that a PR5 website which has 100 outbound links is passing the same "link juice" as a PR5 website that has 5 outbound links.

Just my 2 cents

 

Nice , if it's true.

 

You'll likely have better results if you base your calculations on Brin and Page's original PageRank formula which means that the PageRank value passed by any link is approximately equal to the PageRank of the page on which the link resides divided by the number of links on that page. So, for example, consider two pages with an equal PageRank score - Page A and Page B. If there are 10 links total on Page A and 20 links total on Page B, then the amount of PageRank passed on by Page A will be roughly twice as much as a link on Page B.

For those who want even more accuracy, keep in mind that the PageRank score shown in the Toolbar is widely believed to be a logarithmically-scaled representation of the PageRank score Google uses for its ranking calculations, so each "notch" in Toolbar PageRank value represents a jump from x to the Nth power to x to the N+1th, which accounts for the steepness of the table by whiteblue1942. Unfortunately, this also means that as the Toolbar PageRank score rises, the range of possible true PageRank also rises algorithmically, which makes trying to calculate PageRank based on this information very difficult.

 

You should try making a tool with this. I will be nice info to have.

 

Just giving us random numbers isn't too convincing...

 

I don't think it works but still looks intresting.

 

very interesting.I wonder if it works?

 

i have 101 links and page rank 3 and another site has 100 links and page rank 5

 

Although the presented points table is not 100% acurate as there are other factors too in determining the actual page rank, It is still a good attempt at reading google's mind.

 

That's a piece of nice info. Thanks for that whiteblue1942.
But I would be more grateful if you can provide more quantitative edivence.

 

I think this algo is not true, as for one of my sites, I have 4000+ backlinks, including PR2 or PR3 links, and in the recent PR update I got a PR0

 

Again, just counting links and the PageRank scores of the pages where those links come from is not enough to work with. You also need to consider the PageRank score AND the number of links on the pages where your incoming links come from. To make a simple example, a link from a page with a PageRank score of 3 which only has 10 links on it passes on approximately ten times more PageRank value than another page with an identical PageRank score of 3 but has 100 links on it.

 

ok,i agree with this formula.

 

A good reference info here, thank you.

 

How accurate is this one dude?

 

Wow that is amazing info, thank you!!
